Typical Speeds

When you use the speed formula you find the average speed. It's good to know the "typical speeds" of different modes of transport.

True or false: when you calculate speed=distancetimespeed = \frac{distance}{time} for a journey, you always find the average ** speed for that journey

Typical speeds

1

When we talk about the typical speed of say, a person running or a car driving...

this will always be an average speed.

2

An average person walks 45m45m in 30s30s . What is an average person's typical walking speed in m/sm/s ?

So these are a few typical speeds

Walking, running, cycling, driving in a car and driving in a train.

Steph needs to buy some milk before the shop near her house closes at 6pm. The shop is 360m360m away.

What is the latest time she can leave her house in order to get to the shop a minute before it closes, if she runs at 3m/s3m/s?

Not all people walk at the same speed

1

Which of the following can affect the speed at which a person walks?

hint button

You can select multiple answers

2

There are many factors which can affect the speed with which a person walks.

These include age, terrain, fitness and distance travelled.

Summary!

1

An object which is moving will rarely be moving at the same speed, constantly.

An object will usually be speeding up (accelerating) or slowing down. Therefore we use average speed to calculate the speed.

2

Different modes of transport have different typical speeds

This shows the typical speeds for walking, running, cycling, driving in a car and travelling in a train.
